HINGED CLQSURE.

Application Ied February 14, 1922. Serial No. 536,582.

To all whom it may concern.'

Be it known that I, ELERT A. HILL, a citizen of the United States, residing at `Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hinged Closures, of which the following is a specification.

This invention relates to a door or closure and particularly pertains to a hinged closure of the type embodying a shiftable pivot and the object of the invention is to provide a door or closure mounted to have both reciprocal and pivotal movement whereby the closure may be moved on a straight path of travel to and from its seated position in an aperture and swung to extend to one side of the aperture when in an open position.

Another object is to provide a hinged `door or closure of the above character which is especially applicable for use on the doors of safes, lockers, lock-boxes and the like and is so constructed and arranged that the hinge will be concealed when the door is in its closed position. A furthe-r object is to provide a hinge which is particularly applicable for use in hingedly mounting circular doors, or the like.

With the foregoing objects in veiw, together with such other objects and advantages as may subsequently appear, this invention consists in the parts, and in the construction, combination and arrangement of parts, or the equivalents thereof, as hereinafter set forth and illustrates by way of example in the accompanying drawings in which:

Figure 1 is a, view in elevation of the hinged closure.

Fig. 2 is a View in elevation showing the closure in an open position.

Fig. 3 is a view in horizontal section as seen on the line 3--3 of Fig. 4.

Fig. 4 is a view of the door, a closure as seen in rear elevation as indicated by the dotted line 4-1l in Fig.

Fig. 5 is a detail in section as seen on the line 5-5 of Fig. 4.

More specifically 7 indicates a door or closure which is here shown as circular in form and adapted to close a circular aperture 8 in wall 9, the margin or easing of which aperture is preferably formed of a cylindrical tube 10 here shown as screwed inner wall of the channel being formed by y an annular flange 1st which is designed to closely fit the inner perimeter of the casing 10 in slidable engagement therewith lwhen the door is in its closed position. It will be seen that in order to open or close the door that it must be moved in a straight path to dispose the flanges thereon in and out of telescoping engagement with the casing. The present invention contemplates the provision of a mounting for the door whereby it may be given this reciprocal movement and also to afford means whereby the door may be swung on a pivot to extend to one side of the aperture when in its open position, and in carrying out the invention a stem is pivotally mounted on the inner face of the door and slidablv engaged with a sleeve 16 on the casing. The stem is here shown as connected to the door by a pivot pin 17 which is carried by a yoke or spaced flanges 18 on the door and on which pin the stem is turnable to form a hinge mounting for the door. The sleeve 16 may be aliixed to the casing 10 in any desired manner and the stem is extended therethrough such distance as to afford sufficient slidable movement of the stem that the door may be pulled outward such distance as to dispose the pivot pin forward of the front of the wall so that the door may be swung on the pivot to extend outwardly to one side of the aperture. The stem is fitted with a spring 19 which is here shown as wound on the stem and bears between the sleeve 16 and a collar 20 on the stem in such ianner as to exert a yieldable longitudinal pressure on the sten tending to close the door.

The door may be equipped with any suitable lock or latch mechanism, but is here shown as fitted with a combination lock of the push button type, the specific construction of Which forins no part of this application and therefor does not need to be described in detail herein.

The operation oli' the invention is apparent from the foregoing? it being seen that in opening the door it is necessaryto pull it outwardl7 Von a straight path to Withdraw the iange 14e out of engagement with the casing, and that on pulling the door outwardly, the stein l5 Will slide outwardly in the sleeve 16 in opposition to the spring 1,9 Which will yield under the kpull to which the door is subjected. nrdrawing the stein outwardl7 the pivot pin on thedoor will he disposed such distance in front of ythe Wall that the door inay he swung on the pivot into an open .position as shown in Fig. 2. ln closing theV door it is swung on its pivot to bring the flange le directly in front oit the casing whereupon the door Will he advanced on a straight line to seat the A[lange lllin the casing` and also seat the flange ll of the casing in the channel l2 of the door.

I claim:

l. The Acombination ot a door, a. casing' Sutri-'onnding` an aperture Ato he closed hy said door, a stein slidahly mounted on said casing, a pivot connecting` the inner portion of sai( door to said stein, and a spring acting on said stein yieldahly opposing' inovenient thereof in one direction.

2. The combination of a door, a casing` surroundingI an aperture to he closed by said door, a. sleeve in ysaid casing, a stein slidable leere, a pivot pin connecting the in- A i n ot said door to said stein, and a springacting` on seit stein yieldably opposouti'vard inovenient thereof.

2l. The combination of a casing surroundan aperture formed With an annular l a around the margin ot' ythe aperture, a door adapted to close the aperture having an aniuiiar channel on its inner face to rc ceive said flange, a stein pivotally connected to said door and slidahly carried on said casing i'iorniing` a support or lthe door whereby the latter may he moved on a straight path ot travel to and t'roin the casing and also swung to one side thereof.

il. The combination of a Wall formed with u ard a straight path ot travel in and out of engragreinent with the casing, and a spring acton said stein yieldably opposing outward niovenient thereof normally tending to close the door.

ELERT A. HILL.
